Turn off collect2.
collect2 was added based on the need of -frepo. However, -frepo is currently
broken on -CURRENT (Gcc 2.95.4 20020320 [FreeBSD] / ld 2.12.0 [FreeBSD]
2002-04-10). It is also broken on RELENG_4 (Gcc 2.95.3 20010315 / ld
2.11.2 20010719), so there is no need to MFC collect2 there yet. I have
a feeling the brokeness is due to the wide difference between the libiberty
bits of Gcc 2.95 and the later ld.

Dike out most of the NIS code and replace it with calls to libypclnt.
Rework pam_sm_chauthtok() so it (mostly?) works.
The standard pw stuff still needs to move into a library somewhere.
a.out.5 states that nobody seems to agree on what bss stands for. This is
incorrect, however, as Dennis Ritchie states ``Actually the acronym is "block
started by symbol." It was a pseudo-op in FAP (Fortran Assembly Program), an
assembler for the IBM <models> machines. It identified its label and set
aside space for a given number of words.''

Skip zombies. Add an option (-z) to revert to the historical behaviour

Make the MTRR code a bit more defensive - this should help people
trying to run X on some Athlon systems where the BIOS does odd things
(mines an ASUS A7A266, but it seems to also help on other systems).
Here's a description of the problem and my fix:
The problem with the old MTRR code is that it only expects
to find documented values in the bytes of MTRR registers.
To convert the MTRR byte into a FreeBSD "Memory Range Type"
(mrt) it uses the byte value and looks it up in an array.
If the value is not in range then the mrt value ends up
containing random junk.
This isn't an immediate problem. The mrt value is only used
later when rewriting the MTRR registers. When we finally
go to write a value back again, the function i686_mtrrtype()
searches for the junk value and returns -1 when it fails
to find it. This is converted to a byte (0xff) and written
back to the register, causing a GPF as 0xff is an illegal
value for a MTRR byte.
To work around this problem I've added a new mrt flag
MDF_UNKNOWN. We set this when we read a MTRR byte which
we do not understand. If we try to convert a MDF_UNKNOWN
back into a MTRR value, then the new function, i686_mrt2mtrr,
just returns the old value of the MTRR byte. This leaves
the memory range type unchanged.
I have seen one side effect of the fix, which is that ACPI calls
after X has been run seem to hang my machine. As running X would
previously panic the machine, this is still an improvement ;-)
I'd like to MFC this before the 4.6 code freeze - please let me
know if it causes any problems.

Use 'struct callout' instead of 'struct callout_handle' to avoid
exhausting the kernel timeout table. Perform the usual gymnastics to
avoid race conditions between node shutdown and timeouts occurring.
Also fix a bug in handling ack delays < PPTP_MIN_ACK_DELAY. Before,
we were ack'ing immediately. Instead, just impose a minimum ack delay
time, like the name of the macro implies.

Fix a witness warning when expanding a hash table. We were allocating the new
hash while holding the lock on a zone. Fix this by doing the allocation
seperately from the actual hash expansion.
The lock is dropped before the allocation and reacquired before the expansion.
The expansion code checks to see if we lost the race and frees the new hash
if we do. We really never will lose this race because the hash expansion is
single threaded via the timeout mechanism.
Remove the hard-coded limit of 3 bytes for EUC encodings.
Satoshi NIIMI-san kindly explained that EUC does not limit the byte length to
any arbitrary number.
We now set the limit to the maximum octet length of the codeset and it is
locale-specific.

Fix the play / record rate setting so that it actually works.
The extra microphone channel capability is part of the "normal" ac97

Dotting the i-s:
o Use chunk instead of region when we talk about a memory range.
Region can be confused with region register and we already
call it chunk in machdep.c
o Update the twiddle every 16MB
Back out rev 1.17, it breaks dependencies.
With rev 1.7 one cannot build src/bin/sh -- because make fails to create
the buildtools before trying to use them. Actually it does compile the
buildtools into .o's before trying to use them, but not all the way into
binaries.
o Use aiocblist::fd_file in the AIO threads rather than recomputing
the file * from the calling process's descriptor table.
o Eliminate sharing of the calling process's descriptor table
with the AIO threads.

Fix the calculation that determines uz_maxpages. It was off for large zones.
Fortunately we have no large zones with maximums specified yet, so it wasn't
breaking anything.
Implement blocking when a zone exceeds the maximum and M_WAITOK is specified.
Previously this just failed like the old zone allocator did. The old zone
allocator didn't support WAITOK/NOWAIT though so we should do what we
advertise.
While I was in there I cleaned up some more zalloc logic to further simplify
that code path and reduce redundant code. This was needed to make the blocking
work properly anyway.
Clean up the 1/2 a** committing from Thu, 3 May 2001 11:05:39 -0700 (PDT).
Since then we have living with a GPL'ed find(1) due to grabbing getdate.y
from src/contrib/cvs and its user of the GPL'ed xtime.h. I don't even want
to think about how this could have affected people using our source base.
Would it have been too much trouble to do then what I did now?
Copied getdate.y (public domain) to usr.bin/find and change to use
standard system headers. find(1) now compiles simply with out having
to go to extra effort to do so.

Build fixed on: gcc 3.1 using platforms
- Change killpg1()'s first argument to be a thread instead of a process so
we can use td_ucred.
- In killpg1(), the proc lock is sufficient to check if p_stat is SZOMB
or not. We don't need sched_lock.
- Close some races in psignal(). In psignal() there is a big switch
statement based on p_stat. All the different cases are assuming that
the process (or thread) isn't going to change state out from under it.
To ensure this is true, just lock sched_lock for the entire switch. We
practically held it the entire time already anyways. This also
simplifies the locking somewhat and actually results in fewer lock
operations.
- Allow signotify() to be called with the sched_lock held since psignal()
now does that.
- Use td_ucred in a couple of places.
- Change donice() to take a thread as the first argument instead of a
process so it can use td_ucred.
- Require the target process of donice() to be locked when donice() is
called.
- Use td_ucred.
- Lock the target process of p_cansee() and while reading the credentials
of a process.
- Change the logic of rtprio() slightly so it does it's copyin() if needed
prior to locking the target process.
- rtprio() no longer needs Giant. In theory with full KSE it would still
need Giant to protect p_ucred of curproc for the p_canfoo() functions
but p_canfoo() will be changing to using td_ucred of curthread before
full KSE hits the tree.
- Change procfs_control()'s first argument to be a thread pointer instead
of a process pointer.
- Move the p_candebug() at the start of procfs_control() a bit to make
locking feasible. We still perform the access check before doing
anything, we just now perform it after acquiring locks.
- Don't lock the sched_lock for TRACE_WAIT_P() and when checking to see if
p_stat is SSTOP. We lock the process while setting p_stat to SSTOP
so locking the process is sufficient to do a read to see if p_stat is
SSTOP or not.
- Change the algorithms of the syscalls to modify process credentials to
allocate a blank cred first, lock the process, perform checks on the
old process credential, copy the old process credential into the new
blank credential, modify the new credential, update the process
credential pointer, unlock the process, and cleanup rather than trying
to allocate a new credential after performing the checks on the old
credential.
- Cleanup _setugid() a little bit.
- setlogin() doesn't need Giant thanks to pgrp/session locking and
td_ucred.
- Change the first argument of ktrcanset(), ktrsetchildren(), and ktrops()
to a thread pointer so that ktrcanset() can use td_ucred.
- Add some proc locking to partially protect p_tracep and p_traceflag.
If the receiver runs out of space for an received frame in the internal
FIFO or the in-RAM descriptors it will switch to RX_IDLE from where it
is not restarted.
We used to deal with RX_IDLE by doing a total reinit but this lost
our link and caused a potential 30sec autonegotiation against
switches. This was changed to a less heavyhanded approach, but this
failed to restart the receiver it it were in the RX_IDLE state.
This change adds the RX_IDLE and the RX_FIFO_OFLOW conditions as
triggers for interrupts and receive side processing, and restarts
the receiver when it is RX_IDLE.

Revision 1.17 seems to break a subsequent buildworld (i.e. with the new
make installed) in gnu/usr.bin/groff/src/preproc/eqn (which, being a
build tool itself, is built with the original make during buildworld).
The problem seems to be that in str_concat(), the string is not
terminated when the length of the second string is 0.
This apparently can happen during null suffix rule processing.
o Remove vm_map_growstack() and useracc() from sendsig(). Copyout() and

o Add a comment that osigreturn() and sigreturn() are MPSAFE.
Add support for an additional field to the packages/INDEX file. If
present, this field specifies the media volume that the disc is
contained on. If the volume of a given packages is different than the
current volume of mediaDevice, then the user is prompted --
"This is disc #%d. Package %s is on disc #%d\n"
"Would you like to switch discs now?\n"
If the user selects yes, then DEVICE_SHUTDOWN is called and the user
is then prompted --
"Please remove disc #%d from you drive, and add disc #%d"
This works well for a carefully crafted INDEX file, but more work
needs to be done to sort dependencies on a given package based on the
volume that they reside on, to minimize the amount of disc flipping
required of the user.
This commit is a no-op for normal INDEX files and FreeBSD CDs. These
additional features are only used if the INDEX and cdrom.inf file have
multi-volume support.
Add the concept of a volume to the device and package structures. If
these values are different for a given package, then we must prompt
the user to insert another disc before the package can be installed.
Fix a missed conversion of lld to llu for the uint64_t ks_calls and cast
to unsigned long long.
Don't be too overzealous with the printing of ks_calls in the total
statistics, cut back from 20 to 13 positions to print (which should last
a couple of years easily (20 digits is enough for 3168 years of calls at a
measly billion (10^9) calls per second.)).
High-level changes (user visible):
o Implement -c (clear) to clear previously kept headers (note that
dumps not cleared will remain until -c is used),
o Implement -f (force) to allow re-saving a previously saved dump,
o Implement -k (keep) and make clearing the dump header the default,
o Implement -v (verbose) and make most output conditional upon it,
o Emit minimal output for the non-verbose case with the assumption
that savecore is run mostly from within /etc/rc,
o Update usage message to reflect what is and what's not,
o mark -d as obsolete.
Low-level changes:
o Rename devname to device, for devname mirrors a global declaration
and GCC 3.x warns about it,
o Open the dump device R/W for clear and !keep to work,
o Reorder the locals of DoFile according to style(9),
o Remove newlines from strings passed to warn* and err*,
o Use stat(2) to check if a dump has been saved before,
o Truncate existing core and info files to support force,
o First check for the magic and the version before we complain about
parity errors. This prevents emitting parity error messages when
there's no dump,
o Keep track of the number of headers found and the number of headers
saved to support the minimal output,
o Close files we opened in DoFile. Not critical, but cleaner.
